FUEL SAVER AND DECARBONIZEB.

Application filed January 13, 1923, Serial No. 612,534.

'l To all whom t may concern:

-andl useful Improvements in Fuel Savers and Decarbonizers, of which the following is a specification.

My invention relates to a fuel saver and decarbonizer which is adapted to be at-` tached to the intake pipe of an internal combustionengine between the carbureter and the manifold.

The generalv object of the invention is to provide a device through which air may be ldrawn into the fuel mixture, and in which the air, while passing therethrough, will oe charged with certain compounds that will render the combustion of the fuel more complete and decrease the amount of carbon 'which will be deposited in the cylinders.

vThe invention is particularly adapted to contain camphor or moth balls by which the air, as it passes through the device, be-

-comes camphorated, and not only increases the power which will be obtained from a given amount of gasoline, but also to a considerable degree prevents the adherence and lodgment of the particles of carbon upon the walls of the rin chamber.

The device'is a so adapted to be used for introducing moisture into the cylinders, and it has been found that wheneverY the cylinders become covered with carbon, a small amount of water, usually about one-half pint, introduced slowly by means of my invention while the engine is running, will dislodge carbon and make it unnecessary to go through the laborious process of re- -movingthe. cylinder heads and scrapmg out the carbon.

The preferred form of the invention is illustrated in the accompanying drawing, in which: v f' Fi ..1 is a front elevation of the device attac ed ,to the intake manifold of the' en me.

ig. 2 is a vertical longitudinal Sectio Referring in detail to the drawing. the

'invention comprises a nipple'v which is 'threaded into a hole tapped into the intake ipe 6 between the manifold 7 and the carureter. 8, as shown 1n Fig'. 1. The outer lend of the vnipple is connected with a T- shaped coupling 9, tothe other end of which l is connected a nipple 10 which is in commu- .nication with a depending cylindrical cas ing 1-1 provided at its lowerend with a threaded plug 12 having a central atmos pheric' ort 13- through which air may be drawn y suction of the engine while run ming.

The coupling 9 has a partition 14 extending acrossits centralportion and having an intermediate portion 15, which extends longitudina'lly of the coupling at right anglesto the direction of the stem 16, and having a port therethrough which is controlled by the valve 17. The stem 16 of the coupling has a plug 18 in its outer end throughlwhich extends a threaded stem 19. The valve is provided with a cup-shaped stem 20 within l no air will pass the valve 17, u t when the speed of the engine increases to more than' five miles an hour, the valve will open and the amount of*air passing therethrough will;

vary with the speed of the engine.

The cylindrical chamber 11 is provided near its upper end with an interior flange 23, on lthe under side of which is -se'atedaf screen 24 that covers the opening 25 through which the air must pass in entering the intake pipe. The chamber 11 is long enough to contain two or more camphorated balls 26,

the diameter of the balls being somewhat less than the interior diameter of the chamber, so that they may move freely therein and the lowermost ball is normally -s'eated upon and covers `the-port 13. When the air is drawn in by the suction of the engine, the balls 26 will be readily raised and will rub together and rotate, thus causin camphor to be taken up by the air and rawn into the cylinders. -The screen 24 will act not only as an abutment for the balls, but will strain the air and prevent dirt from being drawn in. f The increased amount Aof air thus supplied to the engine c linders results in a saving of fuel, and t e saturation of air with lc amphor, reduces the amount of .car- 1 bon which will be formed on the walls of the @l v v i may be used with goed results, and in fact,

Va sponge containing water may be inserted in the cylinder il, and the moisture thus supplied will result in a more complete combustion, especially when low grade fuel is used, and will thereby prevent the formav small'amount of water may then be slowly poured into the port i3 while the engine is running, lllhis will result in dislodging the carbon and removing the same from the cylinders in a few minutes without scrap- Vhile lthave shown and described the preferred structure of my invention, it will be understood that various modifications may be made therein without departing .from the spirit of the invention. rllhe del` vice may also be used in other relations wherever 1t is desired to charge a stream ,of air with chemicals.

What is claimed is Y l. The combination with the fuel intake -pipe of an internal combustion engine, of an auxiliary air inlet connected thereto and having a chamber containing camphor balls,

said chamber being located between the aux-l iliary inlet and the atmosphere and having an atmospheric port at its lower end which is normally7 closed by one of the camphor balls seated thereon, said camphor ball acting as a valve for the atmospheric port adapted to be opened by the suction of the engine.

2. The combination with the fuel intake pipe of an .internal combustion engine, of an auxiliary air inlet passage having a chamber-containin camphor balls, a spring-held valve normalfy closing the passage between the chamber and the intake pipe, means for adjusting the tension of said spring, said chamber having a screen `across its upper end between the camphor balls and the valve, and an atmospheric port at the lower end of the chamber, one of the balls being normally held by gravity in a. position. covering the port. f y

3. The combinationyof a pipe having a cylindrical chamber in con` nunication with oneV end and depending therefrom, a plurality of camphorated balls in the chamber, said balls having a diameter slightly less than the internal diameter of the chamber,

a port at the lower end of the chamber, the

lowermost ball normally resting upon and covering said port, said balls belng adapted to be raised and rotated by a current of air passing through the port and through Athe passageway. l

4l. ha comblnation of a plpe having a invia-ir cylindrical chamber connected with its inlet v end and depending therefrom, a screen extending across the upper portion of the chamber below the pipe, an inlet port at the lower endl of the chamber, a plurality of camphor balls within the chamber and of slightly less diameterl than the internal diameter of the chamber, the lowermost ball normally resting on and covering said port, a valve interposedin the pipe, a spring normally closing said valve, the valve being operable by suction applied at the outlet end of the pipe to permit a current of air to pass through the chamber and to raise and rotate the camphor balls.

5. 'llhe combination of a pipe line having a chamber connected with one end adapted to contain a compound for saturating air passing therethrough, a valve chamber interposed in the pipe line and comprising a from the coupling and having a valve adapt`1 ed tocover said port, a spring holding said valve normally closed, and a stem threaded into, the coupling in alinement with the valve stemand spring and adjustable to vary the tension of -the latter.

6. 'lliecombination with the fuel intake pipe of an internal combustion engine, of an auxiliary air inlet connected thereto and having a chamber containing a partially volatile decarbonizing compound inv globular form, said chamber being located between the auxiliary inlet and the atmosphere, and having an atmospheric port at its lowerend which isI nolly closed by one of the globular forms seated thereon, said globular form acting as a 'valve for the atmospheric port adapted to be opened by the suction of the engine.

7. The combination with the fuel intake pipe of an internal combustion engine, of an auxiliary air inlet connected thereto and havin a chamber containing a partially volatile ecarbonizing compound in globular form, said chamber being located between the auxiliary inlet and the atmosphere, and having an atmosphericport at its lower end which is normally closed by one of the globular forms seated thereon, said globular form acting as a valve for the atmospheric port adapted to be opened by the suction of the engine, said chamber having athreaded connection with the' auxiliary inlet, whereb it may be inverted and water poured through lsaid port.

8, The combination with the fuel intake pipe of an internal combustion engine, of

lll@
